The main methods of forming particles become emulsification, coacervation and gelation. These methods can achieve the necessary parameters of the product such as size, porosity and shape by varying process parameters such as temperature, stirring speed and the concentration of solutions. For drying the microparticles vacuum freeze drying was used, which allows to maintain the spherical shape of the particles after drying. The resulting microparticles were examined and photographed using a scanning electron microscope. To determine the cytotoxicity of the microparticles their cell growth and attachment were studied in vitro.</p></abstract><trans-abstract xml:lang="ru"><p>Исследованы способы получения биодеградируемых микрочастиц на основе хитозана, полимолочной кислоты и желатина. Дополнительно были получены образцы микрочастиц желатина и полимолочной кислоты, покрытые коллагеном. Для сушки микрочастиц была использована лиофильная сушилка. Полученные микрочастицы были исследованы in vitro на прикрепление и рост клеток.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>регенеративная медицина</kwd><kwd>микрочастицы</kwd><kwd>биодеградируемость</kwd><kwd>желатин</kwd><kwd>хитозан</kwd><kwd>полимолочная кислота.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>regenerative medicine</kwd><kwd>microparticles</kwd><kwd>biodegradability</kwd><kwd>gelatin</kwd><kwd>chitosan</kwd><kwd>polylactic acid.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Prafulla C., Yoo J.J., Lee S.J.
